User Review: Marmot Men's Ion Windshirt
Price Paid: $27
For a lightweight backpacking wind shirt that has some water resistance, this thing is very nice. 3 oz and packs into a pocket. This did a great job keeping me warm crossing over the Rolands Pass area in CO. But, it is not waterproof. We got poured on with rain and hale and after a few minutes of heavy rain, I was wet. I think this is great outer shell over a fleece or base to keep you comfortable in wind with 40-50 degree temps. But if you do expect to be out in the rain, this will not keep you dry. I love Marmot products and got this on sale at REI.
